Description
Technical Field
The application relates to the technical field of display, in particular to a polaroid, a color film substrate, a display panel and display equipment.
Background
For advanced super-dimensional field conversion (Advanced Super Dimension Switch, ADS) products, due to static electricity, the surface of a thin film transistor liquid crystal display (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) panel can accumulate charges, the charges can affect the internal electric field of the panel, thereby affecting the display effect of the product, even series of defects such as greening of a picture, breakdown of a Gate drive circuit (GOA) area, and the like can be generated, in order to solve the problem, as shown in fig. 1, the ADS and HADS (high transmittance-advanced super-dimensional field conversion) products can coat a conductive layer (Back ITO) 102 on the Back of a color film 103 (or called a color filter) of the color film substrate, act as an antistatic conductive layer, and in the later product of a module, a silver paste 105 is epitaxially coated on a frame sealing glue 106 where the color film substrate and the Array substrate TFT interface, when the charges on the surface of the color film substrate can be conducted to a flexible printed circuit (Flexible Printed Circuit, GND) of the color film substrate 104 through the Back and the silver paste, thereby enabling static electricity on the color film substrate to be conducted to various static electricity conductive surfaces to reach the static electricity, thereby solving the problem that static electricity is conducted into the display. However, this solution increases the procedure of dispensing silver colloid on the module, and the silver colloid has many problems such as abnormality, oxidation, breakage and infiltration into the panel during the coating process, which can reduce the display effect of the product and even seriously affect the quality of the product. In addition, for the current Touch control (Touch) product, when the Back ITO is arranged on the color film substrate, the problem of attaching the Touch product at the Back is caused, but if the Back ITO is not added at the color film side, the antistatic (ESD) capability of the Back product is reduced.
In fig. 1, 101 is a polarizing plate. A common polarizer structure is shown in fig. 2, and includes the following film layers from top to bottom: a protective film 01, a cellulose triacetate film (TAC) 02, a polyvinyl alcohol film (PVA) 03, a compensation film 04, a pressure-sensitive adhesive film (PSA) 05 and a release film 06. The protective film has the main functions of low stripping, static resistance and dirt resistance, the TAC layer can treat different surface treatment effects, the effects comprise common atomization, high transparency and the like, and the PVA layer determines the light characteristics. The compensation film is used for compensating different display modes, the PSA film layer is used for solving the light leakage problem of the polaroid, and the release film is used for enabling the polaroid to have low stripping property.
In summary, the conventional design for preventing ESD on the color film side is to design the color film side Back ITO by silver-dispensing to make the color film side ITO be conducted with the GND line on the TFT side to resist ESD. However, the design can increase the procedure of dispensing silver colloid on the module, and the silver colloid can have abnormality in the coating process, so that the silver colloid is oxidized, broken, permeated into the panel and other problems, the display effect of the product can be reduced, and even the quality of the product is seriously affected. In addition, aiming at the current Touch product, when the Back ITO is arranged on the color film substrate, the process of removing the Back ITO is needed when the Touch product is attached to the Back, but if the Back ITO is not added to the color film side, the ESD resistance of the Back product is reduced.

Detailed Description
The embodiment of the application provides a polaroid, a color film substrate, a display panel and display equipment for static on the color film substrate is led away through the polaroid realization, thereby can omit the conducting layer that sets up on the color film substrate, save the process that needs to carry out when follow-up attached Touch product and get rid of ITO, can also improve product quality simultaneously.
According to the embodiment of the application, one or more transparent conductive film layers are added into the polaroid, for example, one or more graphene layers (of course, other transparent conductive materials can be added) are added into any layer structure of the existing polaroid, so that Back ITO is replaced, the process of removing the Back ITO, which is needed to be carried out when a Touch product is attached later, is omitted, the antistatic effect of the color film substrate can be achieved, and static on the CF substrate can be directly conducted by extending one end of a layer with graphene materials on the polaroid or one end of the whole polaroid to GND of the TFT substrate.
According to the technical scheme provided by the embodiment of the application, the Back ITO is prevented from being coated on the color film substrate of the existing HADS product for conducting static electricity, a foundation is laid for the following lamination of the Touch product, and the antistatic effect can be continuously achieved; and the procedure of coating and connecting the grounding end through silver colloid at the later stage of the module can be omitted, so that the problems of breakage, residue and the like of the silver colloid can be avoided.
For example, as shown in fig. 3, in the embodiment of the present application, transparent conductive graphene is added to the polarizer, specifically, a graphene layer may be formed separately in the polarizer, for example, as shown in fig. 3, and the graphene layer 07 is disposed between the PVA 03 and the compensation film 04, and of course, may be disposed between any two existing layer structures of the polarizer, and is not limited to being disposed between the PVA 03 and the compensation film 04. Alternatively, a plurality of graphene layers 07 may be provided.
Alternatively, embodiments of the present application may also add graphene materials to any one or more of the following layers: a protective film 01, a cellulose triacetate film (TAC) 02, a polyvinyl alcohol film (PVA) 03, a compensation film 04, a pressure-sensitive adhesive film (PSA) 05 and a release film 06. Therefore, the polaroid has an electrostatic conduction function and replaces ITO on the color film side.
Graphene has a perfect two-dimensional crystal structure, and its lattice is hexagonal surrounded by six carbon atoms, and has a thickness of one atomic layer. Graphene is a new generation transparent conductive material, and in the visible light region, the transmittance of four layers of graphene is equivalent to that of a traditional ITO film, and in other wave bands, the transmittance of four layers of graphene is far higher than that of the ITO film. Graphene is the thinnest, most rigid nanomaterial known in the world, which is almost completely transparent, absorbing only 2.3% of the light; the thermal conductivity is up to 5300W/mK, is higher than that of carbon nano tube and diamond, the electron mobility is more than 15000cm < 2 >/V.s at normal temperature, and is higher than that of nano carbon tube or silicon crystal, and the resistivity is only 10 < -6Ω.cm, lower than that of copper or silver, thus being the material with the minimum resistivity in the world. Because of their extremely low resistivity and extremely fast electromigration, it is expected to be used to develop new generation electronic devices or transistors that are thinner and have faster conduction speeds. Since graphene is essentially a transparent, good conductor, it is also suitable for use in the manufacture of transparent touch screens, light panels, and even solar cells.
According to the embodiment of the application, the conventional ITO film can be perfectly replaced by doping the transparent conductive graphene into the existing polaroid structure. Then, the polarizer is softer by the polarizer manufacturing and cutting technology, so that the polarizer is made into the polarizer 201 with a foldable structure as shown in fig. 4, and a part 202 of the polarizer 201 is directly folded over to be connected to the GND metal wire on the TFT side, thereby achieving the effect of conducting static electricity. The arrowed line in fig. 4 represents the route of electrostatic conduction. The graphene material may be uniformly distributed in the entire polarizer or may be distributed in a part of the polarizer, but at least in a part overlapping the grounding end of the TFT side, for conducting away static electricity, and is preferably, of course, distributed in the entire polarizer, so that static electricity of the entire color film can be conducted away after the polarizer is laid on the color film.
The transparent conductive graphene has stronger conductive capability and smaller impedance than ITO, so that the transparent conductive graphene is equivalent to providing a better and more convenient conductive channel for static electricity. When large current static electricity exists, the current is conducted through the polaroid preferentially, and the static electricity cannot attack metal wires in the screen, so that serious abnormal image display results are caused by burning.
It should be noted that, in this embodiment of the present application, the polarizer may be made into the structure shown in fig. 4, that is, the cross section is taken from the direction perpendicular to the plane of the polarizer, and then, as shown in fig. 5, the polarizer in this embodiment of the present application includes two parts, namely, a main body 201 and a branch 202, after the polarizer is disposed on the color film 103, the branch 202 may be lifted and folded, and extends along the sealant 106, and the branch 202 is connected to the FPC GND to form the structure shown in fig. 4, so that static electricity may be conducted away.
Of course, the polarizer may be directly configured to the structure shown in fig. 6 without folding, that is, the polarizer shown in fig. 6 includes two parts, namely, a main body 201 and a branch 202, where the main body 201 is disposed on the color film 103, and the branch 202 is used to extend along the frame sealing glue 106 and connect to the FPC GND, so that static electricity can be conducted away.
The color film substrate provided by the embodiment of the application comprises the polaroid.
Optionally, the color film substrate provided by the embodiment of the application further includes a glass substrate and a color film layer located on the glass substrate, and the polarizer is located on the color film layer.
As shown in fig. 7, in the color film substrate provided in the embodiment of the present application, a color film layer 302 is disposed on a glass substrate 301, and a polarizing plate 303 is disposed on the color film layer.
The color film layer 302 may be a red, green and blue (RGB) color film layer, or a color film layer made of other color resin materials.
